Create search engine to display database on Wix website

Necesito barra de busqueda para mi sitio de web Wix que muestre mi database basado en servicios y codigo postal.
I have a website on Wix. It used to be on Goddaddy, but I had to transfer it to Wix because it was giving me too many problems. Anyways, everything is set up, but I can't figure out a way to connect my database to the search bar I created.
I have inserted all the codes necessary and try so many ways, but at the end, there is always an issue. Either the results won't show or only the value I type in shows. I need someone to create a search engine for me that can classify the results by category and zip code.
Since everything is built, I expect this to be simple and fast for a programmer. Submit your portfolios. If you have worked with search engines before, similar to websites such as Yelp or Yellowpages, please say it in your proposals.

Note: This is not a project for Search Engine Optimization. I am looking for a search bar filter, so don't apply for this project if you are some kind of marketing company or SEO.
